Undefined weak symbols with non-default visibility are seen as local by SYMBOL_REFERENCES_LOCAL. This stops a got indirect to relative optimisation for them, so that pies and dlls don't get non-zero values when loading somewhere other than the address they are linked at (which always happens). The optimisation could be allowed for pdes, but I thought it best not to allow it there too. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Don't optimise got indirect to pc-relative or toc-relative for undefined symbols. ld/ * testsuite/ld-powerpc/weak1.d, * testsuite/ld-powerpc/weak1.r, * testsuite/ld-powerpc/weak1.s, * testsuite/ld-powerpc/weak1so.d, * testsuite/ld-powerpc/weak1so.r: New tests. * testsuite/ld-powerpc/powerpc.exp: Run them.
